Abstract

L'invention concerne les ensembles de traitement de données ayant une mémoire à accès séquentiel. Elle se rapporte à un appareil de traitement de données mettant en oeuvre une mémoire à accès direct dont la capacité équivaut à une piste complète d'un disque magnétique de la mémoire à accès séquentiel. Des registres d'ordre et d'état sont placés aux adresses de début et de fin de chaque secteur d'une piste. Lorsqu'un transfert est nécessaire, le registre de commande de chaque secteur impliqué dans le transfert est programmé par l'identité de la piste. Application à la réduction du temps nécessaire aux recherches dans les mémoires à accès séquentiel.The invention relates to data processing assemblies having sequential access memory. It relates to a data processing apparatus implementing a direct access memory whose capacity is equivalent to a complete track of a magnetic disk of the sequential access memory. Order and state registers are placed at the start and end addresses of each sector of a track. When a transfer is required, the control register for each sector involved in the transfer is programmed by the identity of the track. Application to the reduction of the time required for searches in sequential access memories.
